The Tefen compression tube fitting is made of acetal and connects to tubing on both ends. This union fitting has a threaded connection that can be screwed or unscrewed to connect or disconnect pipes more easily than couplings. This fitting is made of acetal copolymer plastic, which has low moisture absorption, high tensile and flexural strength, and is fatigue resistant. The operating temperatures range from -4 to 194 degrees F. The working pressure for this fitting is up to 200 pounds per square inch (psi).

Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Compression fittings do not require tools or sealants, and are useful in installations where a heat source, such as a soldering torch, is prohibited. When purchasing fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).

Tefen Advanced Plastic Solutions manufactures plastic fittings for pneumatic, automation, and irrigation applications. The company, founded in 1970, meets International Organization for Standardization (ISO) 9001:2000 standards for quality assurance.
